Application filed August 6, 1913. Serial No. 788,257,

To all whom it may concern:

Be it known that I, ALFRED G. F. KU-

Rowsxr, a citizenof the United States, 're-' vice used as an attachment for the rotary platen of a typewriting machine, for holding cardsand other devices, as for instance address-stencils.

An object of the, invention is'to provide a simple, practical and effective construe-- tion, permitting the card holder to be quickly attached to or removed from the platen. The card holder is in the form of a frame curved to conform to the surface of the platen.- It is removably attached to supports, which are rotatably mounted, whereby the card holder may be adjusted'around the surface of the platen to distribute the printing area and prevent uneven wear of the platen surface, or the card holder may' be removed from saidsupports to permit the platen'to be used in the usual way. The supports for the card holder consist of rings or disks 'ournaled at the ends of the platen for adjustment about the platen axle, and

held in adjusted position by pawls on. said supports engaging ratchet disks fixed to the platen. The card holder is removably at tached to said supports by holding devices at its opposite ends, one of the supports having a latch permitting the holder to be removed. The card holder, which may extend the length of the platen, has end guides and an intermediate guide forming with the platen, grooves to'receive and hold the edges of the cards or work sheets which may thus.

be supported at either end of the platen,

and the intermediate guide is preferably ad-- 'justable along the card holder frame to accommodate cards of different sizes.

Other features and advantages will hereinafter appear.

In the accompanying drawings which illustrate a form of my invention applied to an Underwood machine of the front-strike type, Figure 1 is a erspective view of the platen with the car holder attached. Fig. 2 is a perspective view of the card holder and its supports disassembled. Fig. 3 is a fragmentary view of the right-hand end of the platen and the card holder. Fig. 4 is a part sectional end view taken at the righthand end of the platen. Fig. 5 is afragmentary view of parts shown in Fig. 4-, with the latch in released position.

Therotatable platen 1 is fixed on an axle 2 journaled in a platen frame 3. Type bars 4 are adapted to strikethe front face of the platen, or a work-sheet or card for printing or stenciling thereon in the'usual manner.

The platen can be rotated either by the usual line-space mechanism operating on the linespace ratchet wheel 5 secured to the platen axle, or the hand wheels-6 attached to the ends of the axle. The card holder 7 is shown as in the form of a light framecomprising longitudinal-bars 8 connected by end members or bails 9 and 10 and an intermediate member 11, said members being arc-shaped or curved to conform to the surface of the platen, and resting on the laten whenthe holder is in position. Sai parts may be formed from a single piece of sheet material, but the intermediate member 11 is pref.- erably an additional member slidable along the holder to'adjust it for cards of different lengths. Secured to or formed on said members 9, 10 and 11 are projecting flanges or guides 12 adapted to overlie the edges of a card and hold it in position on the platen, said guides being spaced a short distance from the laten to provide room for the cards and aving their ends 13 slightly upturned to permit the cards to be readily inserted. The guides 12 may be thin strips of sheet metal secured to the members 9, 10 and 11, and on the intermediate member 11 may be extended and have their ends 12 upof the card holder, whereby the member 11 is slidably supported and adjustable along 7 the holder to accommodate different sized cards.

The card holder is removably attached to end supports adjustable about the platen axle to permit the card holder to be ad.- justed to any-position'around the periphery of the platen for preventing uneven wear of the platen, and in the form of the invention shown said supports consist of disks or rings 14 and 15 rotatably mounted on the ends of the platen. The ring 15 is freely mounted on the reduced end 16 of the platen, and is held thereon by a ratchet disk 17 secured by screws 18 to the platen and formed with an annular series of ratchet teeth 19 which cooperate with a pawl or dog 20 on the ring 15 to hold the latter in adjusted position. The dog 20 may be lifted by means of a finger-piece 21 against the pressure of a spring 22 to permit the rotary adjustment of the ring. The card holder su port or ring 14 at the left-hand end of the platen has a similar mounting and is held in like manner by a disk 23 secured to the platen and having ratchet teeth 24 cooperatin with a spring-pressed pawl 25 pivoted on t e support 14. The left-hand end of the card holder is removably attached to its support 14 by means of a hook or lug 26 fixed to the end of the holder and projecting into pgsition to enga e beneath a bail or loop 27 fixed on the ho der 14, the latter having a cut-away portion 28 to accommodate the lug 26. The right-hand end of the card holder is secured to its su port 15 by means of a hook or keeper 29- xed on the under side of the frame end 10 and adapted to engage beneath a latch 30 pivoted to thesupport 15. The support 15 is cut away to form a pocket or recess 31 to accommodate the latch 30, its keeper 29 and a latch-holding spring 32.

A. pin 33- on the card-holder frame bears against a shoulder on the support 15 formed by a notch 34, and prevents accidental rotation of the card holder in either direction, said notch '34. having an inclined face to rmit the holder to be readily slipped into atching position. A pin 35 projecting from the latch .30 forms a handle whereby the latch may be moved against the pressure of the spring 32 to release it from the keeper, and permit the right-hand end of the card holder to be lifted from the platen. The holder may then be slipped to the right to release the lug 26, thus removing the holder from' the platen. To replace the holder, the lug 26 is placed in the loop 27 and the right-hand end of the holder then pressed down against "the supporting ring 15, until the latch 30 snaps into positioir over its keeper 29, the ring 15, if necessary, being first rotated to bring the latch 30 opposite the kee er. The keeper 29 being seated in the pee et 31 and bearing against the vertical wall thereof, prevents endwise movement of the card holder.

The card holder may be adjusted about the platen to present a fresh surface of the platen at the printing zone, by depressing the finger-pieces 21, thereby lifting the dogs 20 and 25, and then rotating the card holder with its su ports 14 and 15 to any desired osition reativ'ely to the platen, the latter ing held stationary during such ad'ustment by the usual detent engaging the linespace ratchet wheel.

In the form of card holder shown, two sets of guides 12 are provided, whereby cards or work-sheets may be supported at either end of the. platen. It will be understood, however that the formof work-holder may be \widelyvaried within the scope of my invention. 7

- ,Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
